The artcars at Burning Man (Abraxas Dragon, Mayan Warrior, Robot Heart) are all built on ‘single-layer’ buses. In other words; the plateaus on the roof are welded. That’s because there aren’t many English double-deckers in Bay Area and beyond. That is why we have searched for an ‘open top’ double-decker bus because then a large part has already been done and it will be easier to get through inspections at the RDW…

By Googling we therefore found busman Mike Daly (https://autoline.nl/usedcoachsales/), a decisive double-decker bus dealer (beautiful Scrabble-word!) who has been shipping buses for almost 40 years around the world.
With a stock of +/- 50 buses we soon picked a nice one for our project; a Leyland Olympian from 1983.
